“Monsters are rated according to how dangerous they are against each other, and then according to how dangerous they are to all the other monsters on the list (Unclean Spirits and Wolf-Man have little to fear from each other, for instance, but Wolf-Man is more dangerous to practically everything else). Only if all other metrics are equal is the relative danger to the average human considered–because, let’s face it, they’re all dangerous to the average human. They are monsters.”
